"Really easy to maintain due to the modular design, which keeps costs low, much fewer system suitability failures compared to other manufacturer's instruments. Chemstation/Chemstore is poorly designed for GMP work."

"Agilent 1290 HPLC system is very easy to use and provides us good performance in terms of precision, sensitivity and robustness. It has been used in our R&D labs and routine tobacco testing labs for years. It is recommended to other uses of HPLC systems. "

"I have used a HPLC instruments from various manufacturers but it is Agilent Instruments 1100 and above, that I always return to when I require high performance with ease of use. The Agilent 1200 Infinity series offers this with the flexibility of utilising high pressures (600 bar - 1260 SL) and reduced delay volumes for rapid analysis LC. The modular design also allows for flexibility to configure
The telephone and online support from Agilent is very good although you need to have a registered account to access some online content/applications.
The instrumentation is compatible with Waters Empower 2 and above although a firmware upgrade/downgrade may be needed for some modules.
The highlight for me has always been the quality of the Autosampler modules. The use of mainpass flow through needle was pioneered, and until recently under patent, by Agilent (HP). This results in minimal carryover and large injection volume range, e.g. 0.1uL to 100uL.

"The Agilent 1200 series HPLC is fantastic- from its modular design to ease of use and service. We typically use our system for upstream SEC separation before UV-MALS-RI detection. Our needs also call for orthogonal AF4 separation, and the Agilent 1200 serves as the reliable sample and solvent delivery system to our Eclipse AF4. We use this system regularly, if not daily."

"I had used Agilent 1200 LC system for five years. The 1200 system is extremely easy to operate and have much better sensitivity (compared to 1100 system). I attached the system with Agilent 6320 ion trap mass spectrometer and it served as my real work horse. I am very grateful for the service of the instruments from the Agilent service engineers.
I will definitely recommend the system. The 1200 series has emerged as even better system now. If I purchase the 1200 system, I will definitely look for the most sensitive DAD unit and the pump that can operate at higher pressure (600 bar was for initial 1200 system, but 1290 can operate at 1200 bar). The UHPLC system gives much faster data acquisition and saves time when a number of samples need to be analyzed.

"The HPLC system is a good product, comfortable and easy to use. The software is very simple but sometimes gives us problems (Chemstation SW). Problems communicating with field service personnel can occur if you don't have a purchasing service plan. "

"I have a Quaternary pump, single wavelength machine. EZChrom software is very good. The instrument is also easy to handle operation wise. I have seen that the instrument does not shutdown when an error in process sequence/communication occurs. Also LAN communication gets disrupted on some occasions."

"We bought a 1260 HPLC system in 2013 and we had many problems with the autosampler. Sequence stopped in the middle of runs due to a ''mechanical failure''. Agilent technicians came many times to solve this problem, and they changed almost every part of the autosampler, during 6 months. They finally found that it was an electronic board. After changing this everything was working well. We also had problem with software installation (Ezchrom), with Advanced security settings. Now it's working well. "

"An easy to use and versatile machine. It has performed well for over 7 years. The Chemstation software is easy to operate and understand. The technical support responds very quickly to help me to solve problems."

"User friendly, instrument is operated via simple module which is logically and simply designed. Easy software manipulation which offers a wide range of possibilities. Excellent service, during first two years we had no problems. Then after that any problem was solved immediately via phone or personally next day."

"The HPLC has very user friendly settings. It is very easy to set up methods. The sequence feature is excellent and very easy to use. To confidently be able to set up a sequence and allow it to run for an extended time period is very convenient. The ability to easily run gradient elutions to ensure greater resolution of peaks makes water sample analysis easier."

"Easy to operate- user friendly. Easy screening with Agilent software in method development. Robust- once the method is developed and qualified it never fails QC results. Customer service response within 24 hours."

The Agilent 1200 Infinity Series offers the best system for any application and budget. It is future proof, compatible and upgradeable across the entire series. And it is most trusted with 40 years of innovation and 700,000 modules sold.
